The BECKHOFF CP7721-0001-0040 is an all-round IP65 industrial Panel PC from the CP77xx Economy series, designed for mounting arm installation in machine and plant engineering. Built into a compact aluminum enclosure, this unit integrates a 12-inch TFT display with a resolution of 800 x 600 pixels, an integrated numeric keyboard with 10 PLC special keys and status LEDs, and a single-finger touch screen for operator input.
Equipped with a compact motherboard designed for Intel Atom x5-E39xx processors, the CP7721-0001-0040 provides processing performance for TwinCAT automation tasks and local visualization. Field and network connections are routed through a rear mounting arm adapter featuring four M6 x 18 mm threaded holes. With dual independent Gigabit Ethernet interfaces, a sealed RS232 port, and CFast storage, the device serves as an independent control and HMI terminal directly on the machine without requiring a separate control cabinet enclosure.
